Itchy Skin At Night: Causes, Home Remedies, & Prevention Tips

If you experience itchy skin at night, it is probably because of a condition called nocturnal pruritis. It can be as intense as a prickly sensation you get from a bug bite or an itchy rash and may disrupt your sleep.

There are several factors responsible for the nighttime itch. This includes any fluctuations in the body temperature, dermatological conditions, and circadian rhythm. At times, it could also be psychological. While you may experience itchy skin any time during the day, nocturnal pruritis occurs only at night. This article explores the causes of nocturnal pruritis and ways to manage it. Keep reading to know more.

Causes Of Itchy Skin At Night

You may experience nocturnal itchiness due to natural, environmental, and underlying health-related factors.

Natural Causes Of Itchiness At Night

1. Thermoregulatory Variations

Fluctuation in the body’s natural temperature rhythm may cause nighttime itchiness (1). The body temperature is regulated by the circadian rhythm of your body (a process that regulates the sleep-wake cycle). The core temperature is maximum during the early evening and minimal during the early morning. The temperature also fluctuates as per the sleep stages. The itch intensity rises with increasing body temperature.

Pro Tip

You can also apply a smooth paste of the powdered oatmeal mixed with water on the itchy skin and wrap a moist cloth around it before going to bed. Wash it with cool water the next morning.

2. Transepidermal Water Loss

The skin barrier function alters while you are asleep, causing itchiness. Your skin loses moisture during sleep. This is also known as transepidermal water loss (TEWL), which impairs the skin barrier function and lets the pruritogens (substances causing itchiness) into your system. This phenomenon is commonly seen in those who have atopic dermatitis (1).

3. Low Corticosteroid Levels

The body produces corticosteroids that help control and suppress inflammatory and allergic responses. However, after evening, the corticosteroid levels decrease in the body, reducing the natural anti-inflammatory response. This may cause itchiness at night (1).

Apart from physiological changes, environmental factors can worsen the condition at night.

Environmental Factors Causing Nighttime Itching

Itchy skin is triggered by exposure to environmental factors like:

• Pollen
• Dust mites
• Pet dander
• Dust
• Fragrance
• Bugs
• Seasonal changes
• Change of place
• Painting or renovation at home

Sometimes, the chemicals or dyes in your laundry detergents, scented soaps, and skin care products may also cause itchiness and those sudden bumps on the skin. Apart from these, hot showers, air conditioning, and central heating system can dry out the skin and cause itching.

A vitamin D deficiency in the body is also associated with persistent itching and dry, red skin (2).

Health-Related Causes For Itchy Skin At Night

1. Skin Cancer

As frightening as it can sound, itchy skin can sometimes be a sign of cancer. A study at the John Hopkins Health System found that patients with pruritis or itching are most likely to have cancers of the skin, gallbladder, liver, biliary tract, and hematopoietic system (3).

If itching is accompanied by any unusual and persistent skin growth, rash, or sore, see a board-certified dermatologist immediately.

According to GLOBOCAN, there were about 325,000 new cases of cutaneous melanoma in 2020, or 1.7% of all cancer diagnoses worldwide. For men, the age-standardized incidence rate is 3.8 per 100,000, whereas for women it is 3.0 per 100,000. For men, the cumulative lifetime risks are 0.42%, while for women had a slightly lower risk of 0.33%.

2. Polycythemia

Polycythemia is a condition in which the body has a high concentration of red blood cells that make the blood thick. As a result, it cannot easily travel through the blood vessels and reach the organs. Patients with this condition often experience itching as they may also have high concentration white blood cells that release histamine (4).

3. Other Conditions

A chronic itch may sometimes indicate other diseases, such as diabetes, kidney disease, HIV, overactive thyroid gland, or liver diseases like obstructed bile duct, hepatitis C, or cirrhosis.

Apart from this, you may get itchy skin at night during pregnancy due to fluctuating hormone levels in your body (5). As women age and approach menopause, problems like sweating, hot flashes, and itchiness may become prevalent.

Consult a dermatologist if you suspect an underlying health condition is causing itchiness. Early diagnosis may help determine the root cause of the itching and provide the appropriate treatment quickly. Check out the next section to find out.

Diagnosis Of Itchy Skin At Night

Your doctor will start with a physical examination and medical history to understand your symptoms better. They may ask questions like:

• When did the itching start?
• Did you make any changes to your personal care products or start new medications?
• Can you mention some of the other symptoms you are experiencing?

After collecting the basic information, they may ask you to get one or a combination of the following tests done to determine the cause of your symptoms:

• Blood tests.
• Liver and kidney function tests
• Imaging tests like chest X-rays
• Allergy tests
• Skin biopsy

However, if it is just an occasional itch, there are certain home remedies for skin itching that may provide relief.

How To Manage Itchy Skin At Night

Here are some ways to soothe itchy skin at night:

1. Limit your shower time to 5-10 minutes daily. Ensure to use lukewarm water. Avoid frequent soap application to avoid dryness.
2. Apply an unscented moisturizing lotion or cream all over your body every day right after showering.
3. If you have a rash or your skin is inflamed and red, consult a dermatologist and use itch-relieving ointments as prescribed by a dermatologist. Calamine lotion and creams with camphor and menthol may also provide temporary relief.
4. Use a humidifier to maintain the moisture level inside your room or home. This will prevent dryness, allergens, irritants, and germs.
5. Drink plenty of water as dehydration causes dry skin and may lead to itchiness. Drink at least 8 to 10 glasses of water to keep your skin well-hydrated.

Apart from these few general tips to relieve itching at night, you may also try natural remedies to manage irritation and itch.

Home Remedies To Manage Itchy Skin At Night

1. Take An Oatmeal Bath

Applying colloidal oatmeal (powdered oats) moisturizes the skin, maintains the skin barrier function, and relieves dryness (6). To prepare an oatmeal bath, fill a bathtub with lukewarm water and mix a cup of powdered oatmeal. Soak in this for at least 20 to 30 minutes and rinse your body with water. Do not apply soap.

2. Apply A Cold Compress

A cold compress relieves itching or inflammation and provides temporary relief. It helps slow down the nerve endings and reduces the sensation of itch. You may leave the cold compress or ice pack on for around 10 to 15 minutes or until your itch subsides.

Quick Tip

You can keep your moisturizers in the fridge and apply them before bed to have a direct cooling effect on the skin.

3. Try Wet Wrap Therapy

The therapy involves wearing clothing or placing water-soaked gauze on the affected area and covering it with a dry clothing layer. As the water from the clothes or gauze evaporates, it cools the skin down and relieves itching and inflammation.

4. Take An ACV Bath

Anecdotal evidence suggests that apple cider vinegar may effectively ease inflammation and itching. It helps maintain the pH balance of the skin and may relieve itching.

To make an ACV bath, add a cup of apple cider vinegar to five gallons of warm bathwater and soak in it for at least 10 minutes. Rinse thoroughly and pat your skin dry.

Note: Baking soda is a popular remedy used to relieve itching. However, it is not advisable as it can alter the pH of your skin, leading to dryness, itching, and irritation. Avoid it if you have sensitive skin.

While treatments and home remedies can be helpful, there are a few things you should avoid doing if you have itchy skin at night.

What Not To Do To Prevent Itchy Skin At Night

• Do not go to bed wearing tight or uncomfortable clothes that can irritate your skin. Wear clothes made of soft cotton.
• Avoid consuming alcohol and caffeine before bed. Both can widen your blood vessels, warm up the body, and intensify itching.
• Do not sleep in a warm or muggy room, as overheating can make your body itch. Always keep the temperature in your room at around 60°F to 65°F.
• Do not use scented soaps, creams, and other cosmetics. Synthetic fragrances can irritate the skin.
• Do not scratch the affected area as it may lead to scars, infections, and wounds. Keep your fingernails short to avoid accidental scratches.
